Dears, I did a complete preprocessing workflow for a WV2 scene as described in the CookBook. However, the last step, the residual registration, makes some problems. I need to co-register the WV2 scene on a Spot 5 scene. The homologous point extraction already delivers no homologous points. According to the console output it finds plenty of surf point for the second image, which is the Spot 5 scene, but most times not a single for the first image, the WV2 scene.Since the WV2 scene has been processed with other OTB applications before (incl. OrthoRectification) there exists a .geom file. for the Spot scene no geom file exists and the otbcli_ReadImageInfo does not write an output file (only console output). I therefore redirected the console output into a textfile (see attached metadata.geom). For completeness I've also attached the WV2 .geom file ( 12JAN01-P2AS_P001_toc_ortho.geom). Of course both images are of different resolutions which might by a difficulty for automatic tie point extraction. However, I am not sure if there is another error since at least a few point should be possible to extract.
As substitute for automatic tie point extraction I would also be interested in manual tie point extraction. For this I would need to know the precise format how and which coordinates have to be written in the text file. Is there any experience with using manual tie points with the next tool in the workflow: otbcli_RefineSensorModel? I read about a possibility to manually extract tie points in Monteverdi but can not find any such tool there. Last question: When I do the residual registration as the last step in the pre-processing workflow, does it matter if I already did the orthorectification of the input image which should be adapted? Thanks a lot! Ted -- -- Check the OTB FAQ at http://www.orfeo-toolbox.org/FAQ.html You received this message because you are subscribed to the Google Groups "otb-users" group.
